Meet The Tongue Parasite

In our culture, nature is generally depicted as a beautiful spectacle that is romanticized as a positive force. Time to shed some light on its darker sides. Meet Cymothoa exigua, aka the tongue parasite. You’ll never be alone again once it crawls into your mouth (if you’re a fish). This parasitic crustacean will eat and replace your tongue:

When one of these crustaceans encounters a rose snapper, it enters the fish’s mouth and steadily devours the fish’s tongue. Once it has done this, the crustacean uses hooks on its underside to attach itself to the floor of the fish’s mouth and thereafter serves as a replacement tongue.

Cymothoa exigua is strictly speaking off-topic as it is an old nature rather than a next nature phenomenon. Nonetheless it is a good example of the extreme crudeness of old nature, which we hardly ever encounter among the biomimic marketed products in the supermarket.

Readers question: Does a next nature equivalent of Cymothoa exigua exist and if so, what would it be?
